Augment Agent
Agentic AI pair programmer from Augment Code, designed for professional software engineers working on large codebases. Distinguishes itself from Cursor and Windsurf with persistent codebase memory, large-context indexing, and SWE-bench leadership.
- Vendor: Augment Code
- Site: augmentcode.com
- License: SWE-bench pipeline open-sourced; agent itself is a hosted product
- Editor support: VS Code, JetBrains, Neovim, Vim
Key Claims
- #1 open-source agent on SWE-bench Verified at 65.4% success rate, achieved by combining Claude 3.7 Sonnet (driver) + OpenAI o1 (assembler) — no proprietary models (claim from launch announcement covered in WorldofAI’s video; not independently verified here)
- Large-codebase indexing — handles 39,000+ line repos without context-window collapse, vs. ~10K-token effective limits the video attributes to Cursor
- Persistent memory — learns coding style and past refactors across sessions, similar in spirit to OpenBrain
- MCP support — pluggable APIs, SQL, CLI tools via the standard Model Context Protocol
- Visual debugging — drag-in screenshots for UI/CSS issues; agent suggests fixes and runs only relevant tests
- Next Edit — predictive code edit feature
How It Compares
| Augment Agent | Cursor | Claude Code | |
|---|---|---|---|
| Form factor | IDE extension (multi-IDE) | Standalone editor | CLI |
| Codebase scale | Large (39k+ lines) | Smaller effective context | File-tree with skills |
| Memory | Persistent, cross-session | Per-project | OpenBrain pattern |
| MCP | Yes | Yes | Yes |
| SWE-bench Verified rank | #1 OSS (65.4%) | — | — |
Caveats
- The SWE-bench number comes from Augment’s own blog post and the WorldofAI video — treat as marketing-adjacent until peer-reviewed.
- “Open-source” applies to the SWE-bench pipeline, not necessarily the full agent runtime.
